Differentiate between molar mass, equivalent mass, number of moles and number of equivalents with examples as related to electrochemistry.

Expert Solution

Equivalent mass = molar mass/no of electrons

one faraday electricity passed through electrolyte to form equivalent mass of substance is deposite at electrodes

Cu^2+ + 2e^- --------------> Cu

2F

equivalent mass of Cu = atomic mass of Cu/no of faraday

= 63.5/2 = 31.75 g

no of moles = mass of substance/gram molar mass

no of equivalents = gram molar mass/basicity of acid or acidity of base

Question regarding moles: So I'm having a hard time understanding the relationship between moles, molar mass, atomic/molecular mass, and unified atomic mass units. Is molar mass and atomic/molecular mass the same thing? It seems like atomic/molecular mass is the sum of all the atomic masses in a substance. The units for atomic/molecular mass is unified atomic units and the units for molar mass is g/moles, so it seems like some type of conversion is happening. A Helium atom has an...
